Sample gauge: There is a small hole on top of the unit toward the front.

* NMR Tube: A thin and long glass tube that holds your sample.
+
* Sample spinner: A white piece of plastic that goes around the NMR tube. This serves two purposes:
+
** It keeps the sample centered in the sample tube
+
** It allows the sample to the spun while inside the tube. (This is done with compressed air that is supplied to the NMR). Spinning allows for better spectra to be taken.
